Precision, 16-Channel
17V Analog Multiplexer
Features
Description
Low ON-Resistance (100 Ohms Max.) Minimizes Distortion
and Error Voltages
Low Glitching Reduces Step Errors and Improves
Settling Times. Charge Injection: 5pC Max.
Dual-Supply Operation (±2.7V to ±8V)
Single-Supply Operation (+2.7V to +16V)
ON-Resistance Matching Between Channels: <6 Ohms
ON-Resistance Flatness: 10 Ohms (Max.)
TTL/CMOS Logic Compatible (with +5V or ±5V supplies)
Fast Switching Speed, tTRANS <250ns
Break-Before-Make action eliminates momentary crosstalk
Rail-to-Rail Analog Signal Range
Low Power Consumption, 10µW
Pin Compatible with MAX396
SOIC and SSOP Packages Minimize Board Area
The PS396 low-voltage, CMOS analog multiplexer offers low ONresistance (100 ohms max.), which is matched to within 6 ohms
between switches and remains flat over the specified signal range
(10 ohms max). The PS396 is a 16-channel device.
The PS396 are fabricated using Pericoms 17V silicon gate process.
Design improvements yield extremely low charge injection (5pC
max).
This multiplexer operates with a single +2.7V to +16V supply or with
±2.7V to ±8V dual supplies, while retaining CMOS-logic input
compatibility and fast switching. The PS396 is pin compatible with
the MAX396.

Notes:
2. The algebraic covention, where most negative value is a minimum and most positive value a maximum, is used in this data sheet.
3. Guaranteed by design
4. ∆RON = ∆RON(MAX) RON(MIN)
5. Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the specified
analog signal ranges. i.e., VNO = 3V to 0V and 0V to 3V.
6. Leakage parameters are guaranteed by desgin.
7. Worst-case isolation is on channel 4 because of its proximity to the COM pin. Off-isolation - 20log VCOM/VNO,
VCOM = output, VNO = input to off switch.
8. Leakage testing at single supply is guaranteed by correlation testing with dual supplies.
